Internet down

And then OP doesn't answer, probably because the moderator told them to email. 😓

I still wish we could be advised what the mechanism is behind this pattern of telling users to email Cox when there is no reason to, and locking posts for no reason either. Like how does it serve the moderator? It's extra work for them so they must be getting something out of it. Either it's part of their metric, it's commission based(unlikely), or it's a policy. If you go to other forums, this is nothing like how other moderators work. I won't discuss the topic anymore here though in hope that OP comes back to troubleshoot.

Spent over an hour on the phone with tech support. They are coming out on Monday to replace the modem. 

I highly doubt it's the modem. That is just them following their script. One of the reasons I didn't want the moderator trying to troubleshoot. Make sure the technician check your wiring and signal levels. Also, if they fix anything in your house, there may be a charge.

There are no lights on the modem after it finally boots up. 

What model modem/gateway do you have? No lights like not even the power? The new panoramic gateways(white or black) should only have 1 light. See here for picture of older black one. See here for newer white one. See here for full list.
